rustc: Tweak visibility of some lang items This commit tweaks the linker-level visibility of some lang items that rustc uses and defines. Notably this means that `#[panic_implementation]` and `#[alloc_error_handler]` functions are never marked as `internal`. It's up to the linker to eliminate these, not rustc. Additionally `#[global_allocator]` generated symbols are no longer forced to `Default` visibility (fully exported), but rather they're relaxed to `Hidden` visibility). This symbols are *not* needed across DLL boundaries, only as a local implementation detail of the compiler-injected allocator symbols, so `Hidden` should suffice. Closes #51342 Closes #52795

Upgrade Emscripten targets to use upstream LLVM backend - Compatible with Emscripten 1.38.46-upstream or later upstream. - Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the old incorrect wasm32 C call ABI with the correct one, preserving the old one as wasm32_bindgen_compat for wasm-bindgen compatibility. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.

# only-wasm32-bare
use ignore directives for run-make tests This makes the tests easier to read, and makes it possible to tell which tests aren't being run on the host platform. Fixes #56704.
